fatrace reports file access events from all running processes.
|
|
Its main purpose is to find processes which keep waking up the disk
|
|
unnecessarily and thus prevent some power saving.
|
|
Requires a Linux kernel with the FANOTIFY configuration option enabled.
|
|
Enabling X86_MSR is also recommended for power-usage-report on x86.
